I gotta tell you, I really like Captain Marvel Junior. A lot more than his namesake, and a damn sight more than that Mary Marvel. And he's culturally important in that Elvis Presley copied his haircut (no joke), and later in his career actually wore capes onstage in the same style. Circular reference fans will enjoy the fact that writers of CMJ stories fashioned him into an Elvis fan. Anyway, he's on the team because his alter ego, Freddy Freeman, was crippled by Captain Nazi. So literally, Freddy Freeman is lame. Not CMJ, though. He rocks.
